A multilingual user-facing question form
A PHP cURL request handler that sends prompts + file contents to ChatGPT
A JSON-based language file for UI translations
Optional MySQL logging for user queries
✅ Features
Simple HTML/PHP form for entering questions
File upload support (.txt and .xlsx)
Automatic detection of file type
Excel parsing using PhpSpreadsheet
Language selection system via languages_gpt.json
MySQL logging of all user prompts
Clean cURL integration with the OpenAI Chat Completions API
HTML-safe output rendering
📁 File Overview anonymous-question-form-curl.php
Frontend page containing:

File upload field for .txt or .xlsx
Localization function t1()
Language strings loaded from languages_gpt.json
Form posts to chatgpt-response-handler-curl2.php
chatgpt-response-handler-curl2.php
Backend processor which:
Receives form input
Saves uploaded file into /uploads/
Detects file extension
Extracts text or Excel content
Combines the user question with extracted file content
Sends a cURL POST request to OpenAI's API
Displays ChatGPT's response
Logs user question into a MySQL database
languages_gpt.json
Language file providing UI text for:
English (en)
Finnish (fi)
French (fr)
Russian (ru)
Chinese (cn)
This enables the form to automatically adapt to the visitor's language.
✅ Requirements
PHP 7.4+
cURL extension enabled
Composer (if using PhpSpreadsheet)

OpenAI API key
📦 Installation
Clone the repository
git clone https://github.com/yourname/cURL-session-response-interface-to-GPTchat.git
Install required PHP packages
composer require phpoffice/phpspreadsheet

🧠 How It Works
User submits a question → PHP receives text + file.
File type is detected (txt or xlsx).
Text is extracted:
.txt → file_get_contents()
.xlsx → PhpSpreadsheet
Server builds a combined prompt:
Context:
User question:
PHP sends this to ChatGPT using a cURL POST request.
Response is printed safely using htmlspecialchars().
🌐 Multilingual Interface
All text strings used in the form come from:
language_json/languages_gpt.json
To translate to a new language, simply add a new section:
"de": { "gpt1": "...", "gpt2": "...", "gpt3": "..." }
🛠 Example cURL Request (from the handler) $data = [ "model" => "gpt-4", "messages" => [ ["role" => "user", "content" => $combinedPrompt] ] ];
$ch = curl_init('https://api.openai.com/v1/chat/completions'); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_HTTPHEADER, [ 'Authorization: Bearer YOUR_API_KEY', 'Content-Type: application/json' ]); curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data)); $response = curl_exec($ch);
🔒 Security Notes
Always sanitize output using htmlspecialchars() (already implemented)
Never commit your API key to GitHub
Ensure upload directory is not publicly writable
Consider restricting file size and file type in production
